There was a game called Enemies From Space that I played non-stop about six years ago. It was like Space Invaders, but there were bosses, there was no sound at all (unless I didn't configure something right the last time I emulated it), and your ship's two weapons could be individually changed based on powerups that you collected from shot down enemies.
I still have it sitting on a shelf somewhere, and I have to go through all that crap of reconfiguring DOSBox to play it.
I also recommend and game made by Sierra that has the word "Quest" in it.

Some Sierra classics like The Incredible Machine and Gabriel Knight.
There was a website dedicated to The Incredible Machine where I found a download for all three TIM games, but I can't for the life of me remember the link.
They were very small, the first one being 825KB, and they ran off of executable files.
If I still had the link, I'd post it, but it shouldn't be too hard to find seeing as I just found it by luck on a Google Search.
